Beautify Minified JSON in One Click
Overview
Production APIs and bundlers compress JSON into single-line strings to save bytes. That makes debugging painful. Paste your minified JSON and the formatter expands it with 2-space indentation and syntax highlighting so you can read nested structures clearly.
How to Use This Tool
Copy the minified JSON string from your API response, browser DevTools, or log file. Paste it in the formatter and click Beautify. The indented output appears in under a second regardless of file size.

What is the difference between beautify and prettify?
They mean the same thing in JSON context: adding whitespace and newlines to make the structure human-readable. Some tools call it prettify, others beautify or format, but all produce identical output.
Will beautifying JSON change the data?
No. Beautification only adds whitespace and newlines. Keys, values, nesting, and order are preserved exactly. You can minify the output and it will be byte-for-byte identical to the input.
Can I beautify a JSON array instead of an object?
Yes. JSON arrays (starting with [) are formatted with each item on its own line, with nested objects expanded inside the array.
